Schoolboy error. What about velocity factor?
How do we know this quarter wave will be connected to something that
matches its theoretical 50ohm impedance?
Anyway, even a perfectly resonant and matched length of wire will only
collect signal that exists, and it will not produce a better signal to
local noise ratio than a random length.
